Copolymer compositions were varied from 8 to 54 wt % for both statistical and block copolymers and were characterized by predictable changes in glass transition temperature (75 °C > Tg > 45 °C). When integrated into thin ﬁlm capacitors, block copolymers exhibited the formation of electrical double layer (EDL) at lower frequencies compared to the statistical copolymers of similar comonomer compositions. The materials that formed an EDL all produced a similar maximum double layer capacitance value, with the only diﬀerence being the frequency at which the EDL was formed. Finally, the  \nPIL-containing materials that were utilized in organic thin-ﬁlm transistors (OTFTs) showed a signiﬁcant reduction in operating voltage compared to the poly(MMA) baseline. These results indicate that not only composition but also polymer architecture plays a vital role in the formation of an EDL and determines at which frequency the resulting OTFTs can be operated.

INTRODUCTION  \nThe growing demand for ﬂexible, lightweight, and stretchable electronics has led to great interest in printed organic electronics. Thin-ﬁlm transistors (TFTs) are foundational components of many emerging organic electronic devices such as radio frequency identiﬁcation (RFID) tags, active matrix organic light-emitting-diode-based (AMOLED) displays, and chemical and biological sensors. 1−9 In these applications, lowvoltage operating TFTs are required to minimize power utilization, while maintaining the low processing temperature required to be compatible with plastic substrates. Therefore, novel gate dielectric materials that exhibit both high eﬀective capacitance and low-temperature processing must be developed. 10−12 Electrolyte-gated transistors (EGTs)4, 13 utilize apolyelectrolyte as the gating medium which possess mobile ions that lead to the formation of an electrical double layer that signiﬁcantly increases the capacitance compared to neutral polymers. EGTs can operate in ﬁeld-eﬀect mode by pairing with an appropriate semiconductor. Polycations, for example, possess an immobile positive charge pendant to the backbone that cannot diﬀuse into the n-type semiconductor upon application of a positive gate voltage, where the opposite is true for a polyanion and p-type semiconductor.14, 15 Other  \n © 2019 American Chemical Society 3210  \nresearchers have demonstrated polyelectrolyte-gated thin ﬁlm transistors utilizing both inorganic 16, 17 and organic semiconductors. 18−22 More recently, Thiburce and co-workers fabricated PSS-based polyelectrolyte-gated TFTs by gravure printing methods to develop low operating voltage p-type P3HT device","cbCaidVD15laxMEh","https://ap.wps.com/l/cbCaidVD15laxMEh","pdf",1664835,12,"English","# Abstract\n# Introduction","[{\"question\":\"How were the polymerized ionic liquid (PIL) copolymers synthesized and what was the target?\",\"answer\":\"They were synthesized by nitroxide-mediated polymerization (NMP) to control polymer structure and study how it influences thin-film capacitance.\"},{\"question\":\"What impact does polymer architecture have on electrical double layer (EDL) formation?\",\"answer\":\"Block copolymers form the EDL at lower frequencies than statistical copolymers with similar comonomer compositions.\"},{\"question\":\"How do the PIL-containing materials affect organic thin-film transistor (OTFT) performance compared with poly(MMA)?\",\"answer\":\"They significantly reduce operating voltage relative to a poly(MMA) baseline, and the results indicate both composition and architecture govern EDL formation and OTFT operating frequency.\"}]","Unipolar Polymerized Ionic Liquid Copolymers as High-Capacitance Electrolyte Gates for n-Type Transistors | PDF",1790000319]
